Taskpirate is a pluggable system for TaskWarrior python hooks.
Simpler hooks:
def hook_example(task):
task['description'] += "changed by a hook"
The above is fully working example, no more boilerplate needed.
Much faster execution time in case of multiple hooks (read the more details section).
You'll need tasklib as a dependency:
pip install --user git+git://github.com/tbabej/tasklib@develop
Then you need to drop on-add-pirate and on-modify-pirate into ~/.task/hooks/.
After that, you can just clone any taskpirate-enabled hook as a subfolder into ~/.task/hooks/:
git clone https://github.com/tbabej/task.default-date-time ~/.task/hooks/default-date-time/
In your hook's repository, any file matching pirate_add*.py will be searched for hooks in on-add event. In the same sense, any file matching pirate_mod*.py will be searched for hooks in on-modify event.
Now, the pirate_add_example.py might look as follows:
def hook_example(task):
task['description'] += "changed by a hook"
Any function in pirate_add_example that is called hook_* will be considered as a hook in on-add event. It will be passed the Task object corresponding to the current state of the task being added (as modified by the previous hooks).
TaskWarrior hooks are intended to be simple, but they involve writing some boilerplate code (parsing/formatting json). To allow users to write dead simple code, they can leverage tasklib.
Using tasklib simplifies things a lot, however, it's not a super-lightweight - usage of tasklib can slow down the hook by as much as 30-50ms (usual python hook can probably run in under 40ms), since it imports multiple libraries.
This becomes a problem when user has multiple tasklib-based hooks, since the import time adds up.
Also, note that taskpirate with arbitrary number of hooks will be most likely faster than 2-3 regular python hooks.
You can look into my task.default-date-time or task.shift-recurrence hooks.
